Weable Ghostbusters diplay prop- the Belt Gizmo

Projects Showcase
1

Hi folks. I created this project for my Ghostbusters costume, and I want to share it with others.
I used an Arduino Uno from Elegoo and a DFrobot LCD display shield.

It's an interactive display that prints timed readouts of fictional ghost readings to wear on the belt of a Ghostbusters costume. It has 5 different modes activated by the buttons on the display shield.

It's a pretty simple sketch, so maybe useful if you're doing a different kind of art piece but just want to change the text.

Hi Bruce great work i have ordered the display and have an Uno i can try but. Do you have any details - photos of how it all fits together please ?

Regards

Chris

Thanks, Chris. I’m not using any pins not used by the shield itself. So plugging in the shield is the only connecting to do.

I HAVE mounted it on some blank perf-board I had, using Sugru (or any non-conducting glue/cement you want to use). That allows me to easily secure it in the leather belt-holder that I use.

That fits in the leather holster that is a tape-measure holder. I’ve cut the front strap off it, and re-riveted it back on a little lower and tighter, so that it stretches right under the momentary switches on the shield. The left over stubs where I cut the strap function well (which is why I didn’t remove them). They keep the sides of my mounting board tucked securely in the holder.

Hi Bruce, many thanks for the update that is great. So not wanting to sound stupid once the shield comes i just pug it into the top of the Uno Board ? I assume it only fits one way / location ? This is the Uno i have just opened the package to take the photo. I reckon if i can do this and work out how to programme the code (YouTube here we come) anyone can do this.

well i have tried to upload even tried 3 boards just get this

     System wide configuration file is "C:\Program Files\WindowsApps\ArduinoLLC.ArduinoIDE_1.8.51.0_x86__mdqgnx93n4wtt\hardware\tools\avr/etc/avrdude.conf"

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

     Using Port                    : COM1

     Using Programmer              : arduino

     Overriding Baud Rate          : 115200

avrdude: stk500_recv(): programmer is not responding

it complies ok but wont uplaod i have been on the internet but it means noting to me i have tried all three com ports also. Looks like i have a no go PLEASE can someone help ?

What happens when you try to load any code at all? Like the default sketches in the arduino program? Try Blink for example.

I’d try each suggestion on this link, in order.

Hi Bruce, I tried it on my Laptop uploaded 1st time ?
I need to check the PC settings against my Laptop next.
Sorry to have troubled You.

The Screen has arrived and installed just waiting on my 9V lead an box then i can see it it works.

Cool!! I recommend watching this guy’s video tutorials and following along to begin using arduino. Arduino Tutorial 1: Setting Up and Programming the Arduino for Absolute Beginners - YouTube

Okay, brand new deluxe version of the Ghostbusters G-Meter with SOUND!!!! I added a piezo speaker to the rig, and now it beeps and buzzes and plays tunes.
I've also added new on-screen effects to the different modes.

Here's the new, updated version of the code.

In order for that to work, you'll need to copy and paste this sound library into a second tab in your sketch.

In your sketch window, look for the little tab menu. open that up and click New Tab.
Then put these tones in that tab, and save your project.
